SP 800-90A Hash_DRBG available

[Jeffrey Walton]

Hi Everyone,

We added initial support for NIST DRNGs from SP 800-90A Rev 1. The initial support provides a base class interface for NIST_DRBG, an implementation of Hash_DRBG and its self tests.

The commit of interest is https://github.com/weidai11/cryptopp/commit/5c932fcc3b6333e48ff7cc2405230f4b616eeb50. A commit with documentation followed at https://github.com/weidai11/cryptopp/commit/ef185fa0136f5ef81de0140a5a4ab2bc5e4bc2eb.

We setup a wiki page at https://www.cryptopp.com/wiki/NIST_DRBGs.

Finally, we'll get to the other generators in the future. I want to start working on the HMAC or CTR generator shortly.

Jeff

HMAC_DRBG was added at https://github.com/weidai11/cryptopp/commit/2868452193e32156da4d0bc4ffe113daf4e3e121.

CTR_DRBG looks messy so its not a priority since we have HMAC_DRBG.
